as always ..... BL , centered around 8mA ....... that number being in sweet spot regarding xconductance , associated resistor values and dissipation of part in circuit

however , this one of rare opportunities to toss in whatever you have of Toshiba leftovers (yup- GR and V , too) .... as long you're willing to do some sorting - higher Idss in lower position , lower Idss in upper position in buffer cell ..... and then play with source resistor in lower half , to tidy output node voltage level

Dear Nelson,
Every one has some opinion on LX-mini or open baffle.
We will miss papa amps if we built LX-mini because it requires 100W+100W.
we are running full range with 20W+20W.
So what is your point of view on LX-mini or open baffle with probable FET class AB or chip amps.
It is just some curiosity.
Thanks.
Nag.
